Mechanism of Geocell Reinforcement in Soft Soils-A Review

Infrastructural development is the most important need in present time. Geocell reinforcement is a technique developed for soft soil reinforcement, which is being increasingly used for construction of roads and embankments. All round confinement to the materials is provided by the geocells and thus lateral spreading of the foundation soil on load application is prevented to a great extend. HDPE (high density polyethylene) geocells are the most commonly used geocell type in present time. The three-dimensional, honey comb like structure can provide lateral confinement to soil particles within the geocell pockets.The current paper summarizes the mechanism of geocell reinforcement in soft soils. Geocell reinforcement reduces the magnitude of final settlement and the zone between 0.3B to 0.5B maximize the benefits of soil reinforcement
